This award will provide 52% of the funds required to acquire and install a gas source isotope ratio mass spectrometer in the Department of Earth and Environmental Sciences at Lehigh University. Lehigh University is committed to providing the remaining funds needed. The mass spectrometer system is necessary to carry out the PI's research program supported in part by the National Science Foundation. The main thrust of this research is a study of the processes of crustal mass and energy transfer using field observations integrated with analytical data on the distribution of the stable isotopes of carbon, oxygen, hydrogen, sulfur and nitrogen. Emphasis will be placed on the distribution of nitrogen in metamorphic rocks of the Earth's crust, an area of research pioneered by the Principal Investigator. The stable isotope analytical capabilities of the new instrument will also be used in biochemical and environmental studies programs at Lehigh.

该奖项将提供52%的资金，用于在理哈伊大学地球与环境科学系购买和安装气源同位素比质谱仪。利哈伊大学承诺提供所需的剩余资金。质谱仪系统对于PI的研究项目是必要的，该项目得到了国家科学基金会的部分支持。这项研究的主要内容是利用实地观测结合碳、氧、氢、硫和氮稳定同位素分布的分析数据，研究地壳质量和能量传递过程。重点将放在地壳变质岩中氮的分布，这是首席研究员率先研究的领域。新仪器的稳定同位素分析能力也将用于里海大学的生化和环境研究项目。
